    Specifications and information about the Box extension set with solar panel:

    Included are microphone disc and microphone, controller module for status message delivery (SMS) and intelligent power management, lead gel, and the box itself. A solar panel is included.

    Passive bat monitoring for extended time span

    For planing in advance of wind parks, examining roost use as well as many other long-term monitoring tasks is very useful. Usually activity needs to be recorded for a time span or multiple weeks or even months. A technically challenging task.


    The box extension for the batcorder simplifies this task. The batcorder is contained within a robust plastic box. The borderline microphone is installed in the box cover and additionally protected by a foam ring. A specifically designed control module allows connection of 6V to 17V batteries. The set is sold with a 6V / 12 Ah lead-gel rechargeable battery. This can be recharged using solar panels (optional). Thus, the maximum runtime of the battery is limited by the SDHC card's capacity, and is depending on the two months.

    The box is based on experiences gained from the wind turbine extension, which has been used successfully since more than a year. Thus, we added a microphone test to the box extension, to detect deviances from calibrated sensitivity. If the microphone is damaged, the control module reports this by SMS.

    At the end of each recording interval (night), the box also sends a detailed status update to a freely choosable cell phone number. This message contains the number of recordings of the last night, overall number of recordings, memory capacity of the SDHC card, microphone sensitivity. All you need is a standard SIM card, which you can install yourself easily. Prerequisite is reasonably well cell coverage at the location.

    Reasonable longterm monitoring

    Depending on the expected results long term monitoring can be very powerful. Nevertheless some prerequisites at the location are necessary for optimal use of the batcorder. The box should be spaced to reflective surfaces above, below, to the sides as well as to the front to reduce echos. If installed on the mast, the box should be face-to-face. Electromagnetic fields (power lines and such) as well as known ultrasound sources (for example ultrasound based humidity sensors) should be avoided. We recommend to test before installation if such sources can not be avoided.

    Monitoring for multiple years, as asked by some officials, is possible with state-of-the-art devices not possible without regular maintenance. Microphones age more quickly and should be tested after a year. The device should also be deinstalled before winter to avoid.

    Installation and usage

    When setting up the box you should always fixate the box. At locations with higher visitor rate, the box should be locked and be installed out of easy reach. If installed on the mast, we recommend you to the mast producer, so that you can do the installation.

    Deployed material and accessories

    The standard box extension contains the plastic box, including material for attachment or the bat- teron and control module. The control module and a 6V / 12 Ah lead-gel battery is included as well. One solar panel is included. Can also be ordered without solar panel.

    In addition you need:

    • batcorder 2.0 / 3.0
    • SDHC card
    • SIM card to send a daily status message (prerequisite is a reasonably good cell coverage)
